One way I explore the “heart of health” is attending CME -continuing medical education- conferences. All physicians do, to stay current on medical information and maintain licensure and board certification.
One of the most informative lectures I heard recently was about food allergy, a topic often discussed in the lay literature and media. Much of that discussion is based on personal experiences and opinions which, while interesting, may not be scientifically valid.
I welcomed the chance to hear from an expert to help me counsel my patients. I also have a personal interest since my grandson has food allergies; when he visits me, I have to be careful not to feed him foods he may react to.
The speaker, Kirsten Bennett, Ph.D is a registered dietitian (RD) who specializes in counselling patients with food allergies. She presented data from research studies as well as from her clinical practice, and I’m sharing some of what she said with you.
What is food allergy?
You may assume that any symptom due to eating a food is an allergy but there are many ways food can make us sick, including allergy, intolerance, toxic effects, and infection.
Allergy– immune mediated, that is it involves the immune system with the production of antibodies after exposure to a food; celiac disease is due to food allergy.
Intolerance– does not involve the immune system, no antibodies are produced; this occurs in lactose intolerance.
Some foods such as wheat and milk can cause both allergy and intolerance.
So how do you know the difference? You can’t, without an appropriate medical evaluation, so it is important to see a physician if you suspect food allergy.
Probably up to 10% of the population have true food allergy, but as many as 50-90% of people who believe they have food allergy may not. An accurate diagnosis is important so the condition can be managed properly when appropriate, but not needlessly.

How to diagnose food allergy
Although blood and skin testing may be needed, the history is the first and most important step to identify food allergy. The evaluation may start with the answers to these 9 questions-
- What are the symptoms?
- What food was eaten that may have caused the symptoms and was it eaten before?
- How much of the food was eaten?
- Was the suspect food cooked or raw?
- Has the food ever been eaten without symptoms?
- Was else was the person doing or ingesting at the same time, such as exercise, medications, etc.?
- Have the symptoms occurred without eating the food?
- How were the symptoms treated and how long did they last?

Goals in managing food allergies
Allow the child (or adult) to live as normal a life as possible while avoiding foods that might cause allergic symptoms.
The fear of a serious food allergic reaction can cause a family to forgo normal activities and keep a child isolated. Dr. Bennett suggested these tactics to minimize food allergy anxiety.
- Cook as a family ; Learn how to cook meat and other protein foods
- Take children grocery shopping and engage them in food selection
